83 carbs acting up

83interceptor · 03-23-2008, 09:20 PM

hey guys i had my carbs redone about 6 months ago. it ran great till yesterday it started up fine but after about a mile of riding it stalled out. after the stall it would only start and only stay running with the choke on full. it idles up to 5000 with the choke on but as soon as i put it in gear it stalls. it did this before i had the carbs done.
is it normal for carbs to have problems again after 6 months of off and on riding of atleast once a week

No.

How did it stall? Gradually peters out until you couldn't keep going?

Is your tank rusty? How's your fuel filter?

fuel filter is good it ran great until i tried to take off from a light it would only get to 20 mph then it acted like it was starved for fuel tank is rusty but the filter is clean the pump is good i'm going to the shop who did the carbs today after class to see if they'll fixem for less than the 250 they charged me before

crack open the drain screws on the float bowls and drain out water condensation and rust flakes. Some rust can get through most filters, and draining float bowls periodically will keep the crap from being sucked into carb jets....

what was the longest period it sat unused over the winter??

quick question on the screws on the float bowls, i took those out when cleaning the carbs, do they need to go in all the way? Thanks for the help and sorry to steal the thread!

It may be the screens in the petcock, up inside the tank, that are clogged. Try taking the fuel line off the intake to the pump and see how much flow there is.

...or the entire petcock assembly. Don't ask me why/how, but sometimes you have to replace the whole thing. Luckily they are really cheap (less than $20 if I remember correctly).
